con-facturas DEVICE.

SPECIFICATION forming part of Letters Patent No. 577,687, dated February 23, 1897.

Application filed May 16, 1896. Serial No. 591,789. (No model.)

To all whom, t may concern.-

Be it known'that I, WILLIAM M. J EWELL,

a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Controlling Devices, of which the following is a specification, reterence being had to the accompanying drawings, in which- Figures 1 and 2 are elevations of different parts of the controlling device. Fig. 3 is a vertical section. Fig. 4. is a plan view ot' one of the discharge-rings. Fig. 5 is aview showing a modification.

My invention relates to controlling devices or governors, and has for its object to pro vide a controlling device which will be particularly adapted for use in controlling the discharge from iilters, but it is designed also for use with other mechanisms.

I accomplish the object of my invention as hereinafter specified an d as illustrated in the drawings.

That which I regard as new will be set forth in the claims.

In the drawings, G indicates a water-inlet pipe.

7 indicates a water-tank with which the inlet-pipe 6 communicates, an extension 8 be- 3o ing provided which discharges the water from the inletpipe 6 into the tank 7 near the bot tom thereof.

9 indicates a deflector arranged opposite the bottom of the pipe S to direct the water from said pipe laterally.

10 indicates a butterfly-valve mounted on a stem 11 in the pipe 6.

As best shown in Fig. 3, the tank 7 is provided with an opening at the bottom, around which is a circumferential shoulder 12.

13 indicates a discharge-ring which is elli ptical or oval in shape, having an annular passage. By making the ring 13 oval or elliptical it may be inserted into the tank 7 from below and fitted into place, as Shown in Fig. 3.

14 indicates a funnel arranged below the tank 7 and connected thereto by braces 15.

1G indicates a discharge-pipe with which the funnel communicates.

5o As shown in Fig. 3, the upper portion of the funnel 14. is of greater diameter than the tank 7, thereby forming an opening around said tank through which water may be discharged into the funnel li from without.

17 indicates a pipe which opens into the 55 tank 7 aboutmidway its length.

18 indicates a flexible pipe which is connected with the pipe 17 and with a discharge nozzle 19. As best shown in Fig. 2, the pipe 18 is connected with the nozzle 19 by means 6o of a rigid pipe 20.

21 indicates a guide for the pipe 20.

22 indicates a set-screw for the pipe 20, by which the nozzle 19 may be locked at any desired altitude.

23 indicates a bucket which is suspended by a rod 24: from a lever 25, mounted upon the pivot 1l, which carries the butterliyvalve 10.

2G indicates a coun terbalancing-weight con- 7o nected by a connecting-rod 27 to the opposite arm of the lever 25.

2S indicates a weight connected by links 29 30 to the arms of the lever 25. The object of the weight 2S is to lower the center of 75 gravity and give more stability to the lever 25.

31 32 indicate bars which are arranged over the lever 25 and serve as stops to limit its movement. v

As shown in Fig. l, the bucket 23 is pro- 8o vided with a discharge-nozzle at the bottom to adapt it to discharge water from the bucket into the funnel 14.

The operation of the controller is as follows: With a given flow of water from the 85 pipe (l into the tank 7 the water in the tank 7 will remain at a corresponding height provided the discharge from the tank 7 is equal to the in flow. Acertain amount of water will at the Sametime low out of the tank 7 through 9o the pipes 17 1S and nozzle 19 and be discharged into the bucket 23, from which it will be discharged through the nozzle 33 to the funnel 14.. It, however, the lowof water into the tank 7 increases, the head of water in said 95 tank will increase, consequently increasing the outflow through the pipes 17 18 and nozzle 19 and increasing the discharge into the bucket 23. The weight of the bucket 23 will therefore increase, causing it to overbalance roo the counterweight 26 and rocking the butterfly-valve 10 in such manner as to partially close the pipe G, partially shutting off the Water and reducing the iioW into the tank 7. Should the flow of Water through the pipe 6 decrease instead, the reverse operation will take place, in either case the flow of Water being automatically regulated by the rocking of the lever 25 to keep the discharge from the tank 7 constant. The discharge is originally regulated by regulating the size of the discharge-orifice in the ring 13.

The operation of the bucket 23 is regulated by means of the adjustable pipe 20. Inasmuch as the iiow of Water through the nozzle 19 depends upon the head of water in the tank 7 above said nozzle, the oW maybe increased or diminished by lowering or elevating said nozzle and the valve in the pipe be correspondingly operated. The pipe 2O therefore provides fora more accurate adjustment of the volume of the Water, as Well as a more convenient adjustment, than by the removal of the rings 13. The range of adjustment, however, is not so great.

Instead of using a lever 25 and providing it with the Weight 28 a bent lever 34E maybe provided, the link 24 being connected to one arm of said lever and a counterbalancing-Weight to the opposite arm, the result being that When the lever 34 is rocked the Weight 35 Will be moved outward or inward, increasing or decreasing its leverage.

I have described in detail the consti' uctiou of my improved controlling device, but I do not desire to be limited to the specific details described,as many modifications may be made Without departing from the spirit of my invention.

The form of lever 34 illustrated in Fig. 5 is not claimed herein, as it forms the subjectmatter of another application iiled by me of even date herewith.

That which I claim as my invention, and desire to secure by Letters Patent, is

uid through said conduit, of a tank With which said conduit communicates and into which the liquid is discharged, an outlet from said tank, devices operated by the head of Water in said tank to adjust said valve and thereby regulate the Iiovv of liquid, and a removable ring having a discharge orilice, said ring being substantially oval in shape, substantially as and for the purpose specified.

2. In a controller for regulating the flow of liquid, the combination with a liquid-conduit, and a valve which controls the flow of the liquid through said conduit, of a tank with which said conduit communicates and into which the liquid is discharged, an outlet from said tank, a bucket connected with said valve, a tube communicating with said tank and adapted to discharge water therefrom into said bucket, means for adjusting the outlet of said tube vertically, and means for discharging water from said bucket, substantially as and for the purpose specified.

3. In a controller for regulating the iioW of liquid, the combination With a liquid-conduit, and a valve which controls the flow of the liquid through said conduit, of a tank With Which said cond uit communicates and into which the liquid is discharged, an outlet from said tank, a bucket connected with said valve, a tube communicating With said tank and adapted to discharge Water therefrom into said bucket, a guide for said tube, a set-screw for locking said tube at different heights, and means for discharging Water from said bucket, substantially as and for the purpose specified.

WILLIAM M. JEWELL.
